KPMG Strategy Consultant interview questions

I applied after a recruiting event. The process was very easy and straightforward. They stopped my application abruptly, citing that they needed someone earlier (before I would have finished my studies). I did not get far, so I assume the difficulty level of questions would have increased in the next round.

Very hard interview, I was asked to provide very detaild answers, very stressful interviewer with biter energy. 3 case interview to solve and there is a need to do one more home assignment.
